An electrophysiology (EP) device is system used to perform a test to assess the heart’s electrical system or activities and to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and wire electrodes, which measure electrical activities, through blood vessels that enter the heart. Catheter ablation is a technique used to treat arrhythmia, an abnormal heart rhythm created by a disturbance in the heart’s electrical system. Catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias.
